The purpose of the present study is to examine the effects of one bout of Greek dances and aerobic dance on women's psychological health state. Fifty four healthy women, aged 21 to 55 years, were selected randomly and participated in the study voluntarily. The subjects were divided randomly in two groups: group A (n=27) participated in an afternoon aerobic dance bout and group B (n=27) participated in an afternoon Greek dances bout, both for 60 min. About 5 min before and after the end of aerobic dance bout and Greek dance bout the subjects completed the 37-item Profile of Mood States (McNair et al., 1971), proposed by Shacham (1983), while five additional items were included, measuring exhilaration. In addition, they completed the State-Trait Anxiety Inventory (Spielberger et al., 1970). For data analysis the statistic packet SPSS/PC ver. 18.0 for windows was used. In particular, descriptive analysis was used, as well as the student t-test to evaluate significant differences between measurements (before and after the dances bouts). The subjects had moderate trait anxiety, ranged to 41.00+11.86 and 41.07+8.07degrees for Group A and B, respectively. After the dancing bouts recorded changes significant or relatively modest in magnitude in both groups. More specifically, there were observed an increase in vigor, exhilaration and fatigue, and a decrease in tension, depression, anger and confusion, total mood disturbance and state anxiety. Consequently, one bout of Greek dances, and aerobic dance affect, with the same way and on the same direction, women's psychological health state. It could be said that, the main etiology of the induced state anxiety decrease and mood improvements, is the aerobic mode of the two exercise forms. In addition, the absence of competition, as well as, the fact that Greek dances and aerobic dance are rhythmical and repetitive activities, also constitute important features resulting in positive affect. In conclusion, the participation in a Greek dances bout or in an aerobic dance bout could lead to significant improvements in women's psychological health state through the decrease in state anxiety and the enhancement of mood states.
